Maintaining the 1330
To order a print head kit for the 1330, contact your MTX sales representative. Use the
following part number: 953567-001.
Note: When the 1330 has been printing for an extended time, the print head may
occasionally slow down, start printing unidirectionally, and pause at the end of
each line. This is not a sign of excessive wear. These conditions occur
automatically as a preventive measure when the temperature of the print head
exceeds the normal operating level. As the temperature drops, the print head
will speed up and resume bidirectional printing.
To replace the print head, follow these instructions, referring to Figures 7-1 through 7-4.
Warning
If the printer has been in operation, the print head may be hot. Allow time for the print
head to cool before you attempt to change it.
